Motor Installation Guide

This IS NOT a guide for the do-it-yourselfer. These tips and suggestions are provided for persons with necessary test equipment and proper qualifications.

Before you start to work on the motor, MAKE SURE THE POWER IS OFF. Always turn the power off at the electrical service entrance breaker box or fuse, to prevent electrical shock. To prevent electrical shock when touching the motor, be sure windings are securely grounded to the ground terminal in accordance with local electrical codes. DO NOT work on electrical operations if water or moist operating conditions cannot be avoided.

Basic motor service requires just a few simple tools. To make the job go smoother, be sure to have these tools in your toolbox before you begin working:

Ventilation

Adequate ventilation must be provided to assure normal motor life. To insure extended life, your motor requires sufficient cool, clean air to adequately dissipate the heat generated during operation. Protect the motor form direct sunlight and temperatures that exceed 40°C (104°F). If the ambient temperature cannot be obtained at or below nameplate markings, the next larger horsepower motor should be used.

Moisture

Although certain types of Franklin motors are designed to endure against rain, avoid installing it where it can be splashed or flooded. It is recommended that the motor be mounted at least two inches above the ground.

Altitude

Altitudes in excess of 3,300 feet above sea level will cause the motor to operate at a higher temperature. To compensate for this, the next larger horsepower motor should be used for installations between 3,300 and 9,000 feet above sea level.

Grounding

For maximum safety and protection against electrical shock, a proper ground must be made. Safety Warning: Failure to properly ground the motor for swimming pool installations as specified in article 680 of the National Electric Code may result in serious electrical shock. The motor frame should be grounded as follows: Equipment grounding conductor should be connected to the #10 green headed ground screw provided inside the motor terminal box. Bonding conductor to bond all current carrying metal parts should be connected to the #10 ground terminal provided on the opposite shaft extension end of the motor housing. When the motor is connected to the power supply with one side to ground, connect the "hot" side of the line to "Line 1" terminal on the motor.

Power Source

Before wiring your motor, check to be sure the line voltage, phase, and frequency agree with the information printed on the nameplate. Line voltage should not exceed plus or minus 10% of the nameplate marking while the motor is running. If too low, check for correct wire sizes. If too high, contact your utility company.

Wire Size

To minimize excessive voltage drop during start up and nuisance no starts, make sure your motor is wired with the correct wire size. A motor wired with insufficient wire size can cause several operational problems. Primarily, excessive voltage drop during start up will result in a motor not starting and overheating. Reference the wire size table for correct sizing. This table is not intended for use with Bluffton Motor Works Submersible motors. If you have questions regarding Franklin submersible motors please contact the factory or your dealer.

Fuse Size

Although your Franklin motor may be equipped with an overload protector, you must provide a correctly sized fuse at the breaker box.

Electrical Connections

Wiring connections are located on the motor nameplate. Be sure the voltage connection matches that of the supply line. If reconnection is required refer to the nameplate. For troubleshooting purposes, please contact the factory with your motor model number for more detailed assistance.
